Figure 2From: Optical properties of Ni and Cu nanowire arrays and Ni/Cu superlattice nanowire arraysThe spectra of optical reflection for nanowire arrays measured at different temperatures of 4.2, 70, 150, 200, and 297 K as indicated. The results for a Ni nanowire array (a), a Ni/Cu superlattice nanowire array (b), and a Cu nanowire array (c) are shown.Back to article page
